    For small annulus† patients, the SMART Trial data are clear: Evolut™ transcatheter aortic valve implantation (TAVI) delivers superior valve performance‡ versus SAPIEN™* TAVI with excellent patient outcomes through 2 years.1

    About the trial

    The SMART Trial was a prospective, multicenter, randomized controlled trial conducted to understand how valve design differences between the Medtronic self-expandable (SE) Evolut™ platform and Edwards Lifesciences balloon-expandable (BE) SAPIEN™* transcatheter aortic valve implantation system affect treatment of small aortic annulus (≤ 430 mm2) patients with symptomatic, severe native-aortic stenosis.

    The latest data reported through two years reinforce that these contemporary TAVs behave differently in this patient group, providing physicians with crucial insights to tailor treatment decisions according to individual patient needs.

    Evolut™ TAVI: 12.5%
    SAPIEN™* TAVI: 48.4%

    Evolut™ TAVI: 17.8%
    SAPIEN™* TAVI: 17.6%. p = 0.97
    Hazard ratio, 1.01 (95% CI 0.71, 1.43)

    Clinical outcome composite: All-cause mortality,

    Compared to SAPIEN™* TAVI, only Evolut™ TAVI continues to show strong results across these key components of valve performance‡:

    TAVR risks may include, but are not limited to, death, stroke, damage to the arteries, bleeding, and need for permanent pacemaker.

    Evolut™ TAVI in women

    Only Evolut™ TAVI design has superior valve performance for women compared to SAPIEN™* TAVI at one year.¶,2

    Women’s hearts are different and so is their AS journey. While women are typically underrepresented in major clinical trials,3 the SMART Trial enrolled predominantly women due to its focus on small annulus patients. The SMART Trial is the largest, randomized controlled TAVI trial to primarily enroll women — providing important clinical insights into this patient population.
     

    Drs. Sabine Bleiziffer, Renuka Jain, Roxana Mehran, and Puja Parikh examine the significant healthcare challenge that is the underdiagnosis, under-referral, and undertreatment of women with aortic stenosis.
